If you’ve been arrested for a DUI in South Carolina, you may be feeling overwhelmed by the legal procedures that follow. One of the most crucial elements in a DUI case is the breathalyzer test, which is commonly used to determine whether you are over the legal limit for alcohol consumption. However, it’s important to know that breathalyzer results aren’t always straightforward. The rate at which alcohol is absorbed into your bloodstream can play a significant role in the accuracy of these tests. Understanding how this works may provide a defense strategy in your case.

Understanding Breathalyzer Tests
Breathalyzer tests work by measuring the amount of alcohol in your breath. This is used to estimate your blood alcohol concentration (BAC). In South Carolina, if your BAC is 0.08% or higher, it’s considered illegal to drive. While this might seem like a clear-cut way to determine impairment, it’s important to recognize that the results of these tests are not always as precise as they may seem.
The Science of Alcohol Absorption
When alcohol enters your body, it travels through the stomach and into the bloodstream. From there, it is carried to the lungs, which is where breathalyzers measure alcohol content. However, alcohol does not enter your bloodstream all at once; it is absorbed gradually over time. This delayed absorption can make a breathalyzer reading taken immediately after drinking potentially unreliable, since it might not reflect your BAC at the time you were actually driving. Depending on how quickly alcohol is absorbed into your system, the results could show a higher BAC than was true while you were behind the wheel.
Factors That Impact Alcohol Absorption
There are several reasons why alcohol might be absorbed differently from one person to another. For example, the type of alcoholic beverage you consume plays a role. Drinks with higher alcohol content, like spirits, can be absorbed faster than beer or wine, which might affect how quickly your BAC increases. How quickly you consume alcohol also affects absorption rates. Drinking a large quantity in a short period of time could lead to faster absorption and higher BAC, while drinking over a longer time span could lead to a more gradual increase in BAC.
Another factor that can affect absorption rates is the food in your stomach. If you have food in your stomach when drinking, the alcohol’s absorption is slowed down because the food acts as a barrier. This means that if you were tested shortly after drinking, the alcohol might not have fully entered your bloodstream, potentially leading to an inaccurate BAC reading. On the other hand, if you waited some time after drinking before taking the test, your BAC might appear lower than it was while you were driving, because the alcohol would have had time to be absorbed.
Your body’s metabolism also affects how quickly alcohol is absorbed. Everyone metabolizes alcohol at different rates due to factors such as age, weight, gender, and overall health. For instance, individuals with higher muscle mass may absorb alcohol differently than those with higher body fat, which can alter the BAC results when tested. People with certain medical conditions, such as diabetes or gastrointestinal issues, may also experience different rates of alcohol absorption, potentially affecting breathalyzer results.

How Alcohol Absorption Affects Breathalyzer Results
Breathalyzer results are designed to give an accurate estimate of your BAC at the time of the test, but this may not always align with your BAC at the time of driving. Alcohol absorption occurs over time, and if you were tested shortly after drinking, your BAC could be on the rise, potentially resulting in a higher reading than was true when you were actually driving. Conversely, if a significant amount of time passed between drinking and the test, your BAC could be lower than it was while you were behind the wheel.
It’s also possible that factors like the amount of alcohol consumed and how quickly it was absorbed could create discrepancies in the test results. For example, if you were drinking quickly and consumed a large amount of alcohol just before being pulled over, your BAC at the time of the test may not truly reflect your impairment when you were driving.
Defending a DUI Charge Based on Alcohol Absorption
In a DUI case, it’s crucial to examine the timing of your breathalyzer test. If you were tested shortly after drinking, it may be possible to argue that your BAC was still rising and does not reflect your level of impairment at the time of driving. This type of defense, called the “rising BAC defense,” suggests that your BAC was on the way up when the test was administered, which is not an accurate reflection of how impaired you were when driving.
If food or another substance was consumed before taking the test, this could also be a factor in your defense. The presence of food in your stomach can slow alcohol absorption, which may make your BAC appear higher than it would have been if you had been tested at a different time.

Additionally, breathalyzer results can be challenged if there are issues with the machine itself. Breathalyzers are not infallible, and problems like faulty equipment, improper calibration, or errors in the administration of the test can lead to inaccurate results. A skilled lawyer can look into these technicalities and use them to challenge the validity of the breathalyzer results.
Medical conditions or medications may also play a role in how alcohol is absorbed into your system. For example, if you have a condition like diabetes, your metabolism may process alcohol differently, which could affect breathalyzer readings. Presenting medical evidence to support this claim could strengthen your defense.
Steps to Take If You Are Facing a DUI Charge

Several factors can affect the results, and an experienced DUI attorney can help you navigate these complexities. By examining the timing of the test, your drinking habits, and any medical conditions that might affect alcohol absorption, your lawyer can build a strong defense on your behalf.
